Labor rate guide says labor to replace is about 1.5 hours. I looked at the repair instructions, it did not seem complex to replace the engine oil pan. Oil pan bolts get tightened to 11 ft/lb this engine doesn't use an oil pan gasket from new, Saturn use a sealer (any auto parts store has a comparable product), Felpro may list a gasket between the oil pan and engine.
The exhaust must ne removed. There are three exhaust bolts toward the front or the car and three on the center of the exhaust where it comes together on the middle of the car. I just replaced mine last week. Really easy fix once the exhaust is removed.
